Snap link



Dec. 17, 1929. J. H. LOISELLE ET AL SNAP LINK Filed Oct. 22, 1928 Jwwnto Patented Dec. 17 1929 JOSEPH H. LOISELLE AND NATHAN B. COHEN, OF DULUTH, MINNESOTA, ASSIGNOB-S OF ONE-THIRD TO FRANK P. LOISELLE, OF DULUTH, MINNESOTA SNAP LINK Application filed GctOber 22, 1928. Serial No. 314,092.

This invention relates to anti-skid chains for automobiles and has special reference to a novel form of attachment of the crosschains to the side chains of such a device.

The principal object is to provide asnaplink attachment for the ends of the cross chains which will permit of convenient attachment and detachment of same.

Another object is to produce such a device whereby such advantages may be accomplished with the common cross-chains now in use.

Still another object is to provide such means which may be readily applied to the cross-chains Without special instruments for such puprose.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing, forming part of this application and wherein like reference characters indicate like parts:

Figure 1 is an elevation of one of the improved spring attachments for application to the terminal link of a cross-chain;

Figure 2 is a side elevation of Figure 1;

Figure 3 is an elevation taken opposite to that shown in Figure 1 with the device leaning towards the observer; and

Figure 4 is a perspective view of the end of a cross member of an anti-skid chain with the device installed for use.

The invention broadly resides in opening the free ends of the terminal link of a cross chain and removably installing therein a spring tongue, whereby a snap link is provided. V

1 represents the terminal link of a cross chain the connecting link of which is illustrated at 2. 3 represents the free ends of the stock of which the terminal link is composed and these as before stated are opened for convenient engagement with the side chains of the anti-skid device. Within the opposite end of the terminal link is installed the flat spring member 4: which is bent upon itself as at 5 intermediate of two pairs of laterally disposed wing-like. projections 6 and 7, these being so shaped and spaced as to conveniently slip over one of the sides of, the loop of the terminal link and readily susceptible of turning therein into the position shown in Figure 4 when the opposite or free end is slipped under the terminals 3 of the link. For proper holding registration with the link the free end of the spring member 4: is formed with projecting ear-like portions 9 slightly turned upwardly at'their outermost extremity and intermediate of which is formed a samewhat V-shaped hump 10, so that when in the position shown in Figure 4 the two rounded terminals of the link lie one within each space intermidate of the hump and the side wings, where the normal spring action of the member 4 holds the opening in the link closed. The member 4t is of sufiicient length to occupy a greater space than that intermediate of the connecting link 2 and the terminals 3 so that it is not possible of dislodgment except as the free end thereof is moved laterally from beneath the terminals 3 and the biting engagement of the foremost edges of the wings 6 counteracting the biting engagement of the rearmost edges of the wing 7 provides ample holding effect to the loop in the link.

Having thus described our invention, what we claim and desire .to secure by Letters Patent, is: j I

1. A sprin member for a snap link, the latter having a loop at one end and a hook at the opposite end, characterized by having ahook-like member at one end providedwith laterally disposed ears for readily removable engagement with the loop of the link, and the opposite end acting as a closure for the hook of the link.

2. A snap link comprising in combination a an elongated link having a loop atone end, a hook at the opposite end and a removable spring closure member for the hook, said member having laterally disposed wing like members formed integral therewith designed to impinge the opposite sides of the loop.

3. A snap linkcomprising in combination an elongated link having a loop at one end, i

a hook at the opposite end'and a removable spring closure member, one end thereof extending beneath the loop and the opposite end bent upon itself intermediate of two pairs "of laterally disposed wing-like members integrally formed therewith and designed to impinge the opposite sides of the loop.

4. In combination an elongated linkhaving a loop at one end and a hook at the opposite end, and a spring closure member for the hook, one end of said spring member being removably engaged with the loop and having two pairs of wing-like members formed integral therewith for such engagement and the opposite end of said spring member being engageable with the hook.

5. A spring member for a snap link hav- .ing one end bent upon itseli and having formed integral therewith opposed pairs of wing-like'members forremovable attachment to the link, and the opposite end of said spring member being shaped to act as a closure 'forthe link.

6. A spring member for a snap link having one end bent upon itself and having formed integral therewith opposed pairs of Wingdike members for removable attachment to the link, and the opposite end of said spring member being shaped to act as a closure for the link, and means whereby the spring member may be removed from the link'by rotation'in either direction.

7 A removable spring clip, for a snap link the latter having a loop at one end and a hook at the other end, characterized by havingjahook-like member at one end provided with laterally'di'sposed ears for removable engagement With opposite sides of the link and theopposite end acting as a closure for thehook oi the link.

8. A spring member for a snap link having a'loop at one end and a hook at the other, one end of said spring member being bent uponitself for removable attachment to the link by rotation in either direction and the opposite end shaped to act as a closure for the link.

In testimony whereof we aflix our signatures.
